The mol-ecule of the title compound, [CuI(C(19)H(20)Cl(2)N(2))], lies across a crystallographic mirror plane. The coordination around the copper centre is distorted trigonal planar, with a bite angle of 94.40 (7)°. A six-membered chelate ring is formed by the coordination of iminic N atoms of the bidentate ligand to the Cu(I) atom, adopting a chair conformation. This conformation is required if the local symmetry of the metal coordination site is in accordance with a mirror plane that passes through the metal atom normal to the line connecting the N atoms. The dihedral angle between the benzene rings is 78.66 (5)°. The crystal structure is stabilized by weak inter-molecular C-H⋯π inter-actions, which link the mol-ecules into chains along the b axis.
标题化合物[CuI(C₁₉H₂₀Cl₂N₂)]的分子位于一个晶体学镜面平面上。铜中心周围的配位呈扭曲的三角平面构型，咬角为94.40 (7)°。双齿配体的亚胺基N原子与Cu(I)原子配位形成一个六元螯合环，呈椅式构象。如果金属配位位点的局部对称性与一个垂直于连接N原子的直线且穿过金属原子的镜面平面一致，则需要这种构象。苯环之间的二面角为78.66 (5)°。晶体结构通过弱分子间C-H⋯π相互作用得以稳定，这些相互作用将分子沿b轴连接成链。
